The reader's concern about circularity is real but cannot even be investigated until the true manuscript is retrieved. I therefore agree partially: the reader identified the right scientific risk, but the document-level mismatch is the immediate blocker. The verdict should remain UNVERDICTED because the absence of evidence, not a demonstrated flaw, is what prevents assessment.

There are no machine-checked proofs, reproducible numerical code, parameter-free derivations, or simulation diagnostics by which to assess the result.

The full text is arXiv:2508.15178, a black hole polarization study by a different group. So the only thing I can fairly engage with is the abstract of Huang et al. That puts a hard limit on what a referee can say.\n\nOn the abstract alone: the project is a legitimate extension of the authors' earlier unification idea. They showed in 1D that localized chromospheric heating could explain both the evaporation-condensation and direct injection routes to prominence formation, with heating height as the selector. Replacing ad hoc heating with reconnection-driven heating in 2D MHD is a real step forward. If the simulations deliver what the abstract promises, it would be a useful result for the prominence community.\n\nSoft spots, in proportion. First, the mismatch means no equation, figure, or numerical result can be checked. That is not a flaw in the physics, but it is a serious problem for this submission. Second, the abstract's wording that 'the localized heating is naturally realized by magnetic reconnection at different heights' raises the worry that reconnection sites are effectively chosen by initial and boundary conditions rather than emerging from the dynamics. If the height dichotomy is imposed, the model becomes circular. That concern is real, but it is a question for the actual manuscript, not something I can settle from the abstract. Third, there is no description of the MHD code, resolution, or energy balance, so I can't judge whether the heating is truly self-consistent.\n\nWho is this for? Solar physicists studying prominence formation; it is a modest subfield-level contribution. The citation pattern can't be checked, but the abstract appropriately references their previous work.\n\nRecommendation: don't desk-reject the idea, but do ask for the correct PDF. If this is an arXiv identifier mix-up in the submission system, get the right file and send it to a referee who can check the numerical setup and the circularity question.
